Silicon carbide FRP

Silicon carbide (SiC) with quartz sand, petroleum coke (or coal), wood as a raw material by high temperature resistance furnace smelting made. Silicon carbide also exists in nature, a rare mineral moissanite. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other high-tech non-oxide refractory materials, and silicon carbide is the most widely used, most economical, can be called emery or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal), wood (need to increase the production of green silicon carbide salt) and other raw materials in high temperature resistance furnace smelting. China's industrial production is currently divided into black silicon carbide, silicon carbide and green silicon carbide are two, are hexagonal, a specific gravity of 3.20 - 3.25, the hardness of 2840 ~ 3320kg / mm2.
